Description
Technical field
The utility model relates to the structure of a kind of masonry or cubic boron nitride drilling tool working lining, is applicable to masonry or the cubic boron nitride drilled products of the hard brittle material such as glass, pottery, the specific alloy processing needing to obtain good suface processing quality.
Background technology
At present when using masonry or cubic boron nitride drilling tool to carry out Drilling operation for hard brittle material, because material fragility is large, chip situation is easily there is in hole and material surface contact edge, chip place can form stress and concentrate, and very little chip also can make product to be processed crack from the position of chip, cause fracture.When actual boring work, the material ring-shaped with tapering is made in the working layer materials ring top of thin-walled drilling tool by us, after drill bit terminates Drilling operation, there is the working lining with the conical surface to carry out chamfer machining to the edge in aperture, use and make chamfering working lining compared with the diamond of detailed catalogue number or cubic boron nitride abrasive materials, the position grinding producing chip is processed into oblique angle transition, reduce the damaging influence that chip brings, also meet the requirement of product to outward appearance that some have decoration function simultaneously.Creep into part at drilling tool, generally adopt diamond compared with coarsegrain or cubic boron nitride abrasive materials, the diamond of the employing smaller particle size of chamfer site or cubic boron nitride abrasive materials.Thin-walled drilling tool operationally; centre leads to cooling fluid; to guarantee that the heat produced in boring work is taken away in time, but when work is carried out in chamfering position, because fine size, working lining are again the overall annulus of a continuous print; and the working lining of chamfering position creeps into partly thicker relatively; Grinding Contact area is large, and cooling fluid not easily enters operating position, often can shine into grinding position overheated; produce the phenomenon of the sparking burning of bits, drilling tool and workpiece are damaged.
Summary of the invention
The utility model relates to the structure of a kind of masonry or cubic boron nitride drilling tool working lining, it is characterized by: the working lining part of drilling tool is the sintered body material ring containing varigrained diamond or cubic boron nitride of sintering, sintered body comprises the thin-walled hollow combining coarse diamond or cubic boron nitride abrasive materials and creeps into part (1-1) and combine the band tapering chamfered part (1-2) of fine grained diamond or cubic boron nitride abrasive materials, creeps into partly and chamfered part is the sintered body combined.Circumferentially uniform cooling fluid through hole (1-3) and cooling liquid bath (1-4) in the junction of tool part and chamfered part; Cooling fluid through hole one end communicates with drilling tool working lining endoporus, and the other end communicates with cooling liquid bath.Cooling fluid through hole is positioned at the junction of creeping into position and chamfered part working lining, circumferential length is between 1/20 ~ 1/5 of drilling tool diameter, axial height is between 0.5mm ~ 1.5mm, and radial depth is the actual grade of working lining, and shape is rectangle, annular, triangle, circle; Cooling liquid bath is offered at the chamfered part of working lining, one end of cooling liquid bath is communicated with cooling fluid through hole, circumferential length is between 1/20 ~ 1/5 of drilling tool diameter, axial height is between 1.5mm ~ 3mm, radial depth is the working lining degree of depth retaining the chamfering position after creeping into the working lining external diameter of position, and shape is rectangle, annular, triangle, circle.According to drilling tool direction of rotation operationally, position the offering below at cooling fluid through hole of cooling liquid bath.The quantity of offering of cooling fluid through hole and cooling liquid bath can according to drilling tool specification circumference uniform distribution 3-15.
The utility model is solve cooling problem when being with the drilling tool of chamfering structure to work in chamfering position, and the technical scheme adopted is:
Masonry with chamfering structure or cubic boron nitride drilling tool working lining be on the thin-wall material ring (1-1) creeping into part integral sintered go out with the thicker material ring of the conical surface as chamfering working lining (1-2), creeping into part at thin-walled adopts compared with the diamond of coarsegrain or cubic boron nitride abrasive materials, the more fine-grained diamond of employing of chamfer site or cubic boron nitride abrasive materials sinter the overall work layered material ring needing shape specification into simultaneously through sintering process, creep into part and chamfered part be the sintered body combined.Creeping into junction circumferentially uniform cooling fluid through hole (1-3) and cooling liquid bath (1-4) of part and chamfered part; Cooling fluid through hole one end communicates with drilling tool working lining endoporus, and the other end communicates with cooling liquid bath.Cooling fluid through hole is positioned at the junction of creeping into position and chamfered part working lining, circumferential length is between 1/20 ~ 1/5 of drilling tool diameter, axial height is between 0.5mm ~ 1.5mm, and radial depth is the actual grade of working lining, and shape is rectangle, annular, triangle, circle; Cooling liquid bath is offered at the chamfered part of working lining, one end of cooling liquid bath is communicated with cooling fluid through hole, circumferential length is between 1/20 ~ 1/5 of drilling tool diameter, axial height is between 1.5mm ~ 3mm, radial depth is the working lining degree of depth retaining the chamfering position after creeping into the working lining external diameter of position, and shape is rectangle, annular, triangle, circle.According to drilling tool direction of rotation operationally, position the offering below at cooling fluid through hole of cooling liquid bath.The quantity of offering of cooling fluid through hole and cooling liquid bath can according to drilling tool specification circumference uniform distribution 3-15.Thin-walled drilling tool operationally, centre leads to cooling fluid, cooling fluid is thrown out of by cooling fluid through hole when drilling tool High Rotation Speed, when starting working in the chamfering position of drilling tool working lining, the cooling fluid be thrown out of is blocked by the hole wall of workpiece and is flowed to cooling bath and be stored in cooling bath, lowering the temperature timely to the machined surface of chamfering working lining position and workpiece, reach cooling effect.
The utility model, by the cooling fluid through hole that the band masonry of chamfering or the working lining of cubic boron nitride drilling tool design and cooling liquid bath, avoids grinding position when the working lining of drilling tool in chamfering position works overheated, the phenomenon of the sparking burning of bits of generation.Make the life of drilling tool, improve working (machining) efficiency.
